Ngokuphuculwa okuqhubekayo kwemveliso kunye nemigangatho yokusingqongileyo, izixhobo zokufudumeza kunye nokupholisa iindawo zokugcina zibe zixhobo eziqhelekileyo kumashishini amaninzi. Inxalenye yomkhusane yomnyango okhawulezayo we-zipper ayinayo nayiphi na intsimbi yokuqinisekisa ukhuseleko lwezixhobo kunye nabasebenzi, kwaye umnyango we-zipper okhawulezayo unomsebenzi obalaseleyo wokuzibamba. Ngelo xesha, inomsebenzi wokuzilungisa, nangona ikhethini lomnyango lichithwa (njengokubetha i-forklift, njl.), Ikhethini iya kuphinda ilandelele ngokuzenzekelayo kumjikelezo wokusebenza olandelayo.
